Paper Abstract

Based on real-time diagnosis of health status of reinforced concrete beam, intellectual supervisory layer of carbon fiber reinforced concrete (CFRC) was set up at the bottom of girder structure. The intrinsic law of tensile sensitive characteristic of CFRC was studied and the electrical property collection and the stress transformation system of structure intellectual layer were established. It depends on the premise that carbon fibers are conductive, and that a stable relationship between electric resistivity and stress field exists. The security self-diagnosis of girder structure was fulfilled through online real-time monitoring and evaluation on electrical signal of intelligence layer of reinforced concrete beam.
